Abstract
A drive system drives a plurality of whorls rotatable about respective whorl axes and having radially outwardly directed faces centered on the respective axes, forming a discontinuous whorl surface, and of a predetermined whorl width measured parallel to the respective axes. The system has an endless flat drive belt extending past the whorls generally perpendicular to their axes and having a first belt surface radially directly confronting the whorl surface and of a predetermined axial belt width measured parallel to the axes and pusher rollers bearing radially inward against the belt and urging the belt surface toward the whorl surface. A ridge is formed on one of the surfaces, radially engages the other surface, holds the rest of the other surface out of contact with the one surface except at the ridge, and is of a predetermined ridge width in contact with the other surface and measured parallel to the axes equal to at most one-third of the belt width.
